Grandes Misiones de Exploración del Sistema Solar
Overview
1 – Magnetism is everywhere in the universe. Examples
2 – The adventure to measure the magnetic field in Space
3 – Space magnetic fields measurement. Desire versus Practical reasons
4 – Magnetic Cleanliness Concept
5 – Types of magnetic measurements
6 – The approach of miniaturized compact magnetometers
Magnetism is everywhere
The Magnetic Field of the Earth
Shields the planet protecting life on Earth
“Relatively close” magnetic fields
Field of the Sun
Planetary Fields
The Earth
Jupiter
Saturn
Uranus
Neptune
Other magnetic fields
If it were for magnetic fields to be measured
in Space…
every space mission should have
magnetometers on board
Magnetic Sensors for Space?
And beyond
Venus
Mercury
The Earth
Mars
Ceres
Jupiter
Saturn
Uranus
Neptune
Pluto, Eris
Makemake, Haumea
Once we are there we cannot expect any help
Are there magnetic sensors capable to accomplish
the technical requirements with enough robustness?
The heritage of the military sensors
(Technology Readiness Level-TRL)
AEROSPACE

What is the subject of Space Magnetometry about?
Magnetic Cleanliness…a headache
Every vehicle has a magnetic signature
NANOSAT-01
OPTOS
Magnetic Signature attenuates very fast with distance
